Abstract
A high-voltage disconnector includes first and second contact elements movable along a disconnecting axis with first and second latching elements fixed thereto, respectively, a drive system for moving the first contact element in an opening direction along the axis to open the disconnector, and a restoring system for restoring the second contact element counter to the opening direction. With the disconnector closed, the first and second latching elements are arranged in a latched connection with one another. During an initial phase of the movement of the first contact element in the opening direction the latched connection initially remains, and the second contact element is carried along by the first contact element in the opening direction. During a disconnecting phase, the latched connection is released, the second element is restored by the restoring system counter to the opening direction, and the second contact element is disconnected from the first contact element.
